Date: Mon, 20 Mar 2023 08:34:15 +0000 [thread overview]
Message-ID: <bug-109206-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109206
Bug ID: 109206
Summary: [13 Regression] gcc/fortran/class.cc:2768:14: runtime
error: load of value 4139789424, which is not a valid
value for type 'bt' since r13-6747-gd7caf313525a46
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: pault at gcc dot gnu.org
Target Milestone: ---
The following test-case fails with UBSAN enabled:
$ cat finalize_38a.f90
module testmode
type simple
integer ind
end type
type, extends(simple) :: complicated
real rind
contains
final destructor4
end type
contains
subroutine destructor4(self)
type(complicated) self
end
function constructor2(rind)
optional rind
type(complicated), allocatable :: src(:)
integer sz
if (present (rind)) then
src = [(complicated (ind0, rind0), i = 1, sz)]
end if
end
end
$ /dev/shm/objdir2/gcc/xgcc -B/dev/shm/objdir2/gcc/ finalize_38a.f90 -c
-std=f2008
finalize_38a.f90:19:56:
19 | src = [(complicated (ind0, rind0), i = 1, sz)]
| 1
Warning: The structure constructor at (1) has been finalized. This feature was
removed by f08/0011. Use -std=f2018 or -std=gnu to eliminate the finalization.
